Future Progressive: I will be coming

Present Perfect Progressive: I have been coming

Perfect Tenses - Thì Hoàn thành

The three perfect tenses in English are the three verb tenses which show action

already completed (The word perfect literally means "made complete" or

"completely done.")

They are formed by the appropriate tense of the verb to have plus the past

participle of the verb

Present Perfect: I have seen it

(Present tense of to have plus participle Action is completed with respect to the

present.)

Past Perfect: I had seen it

(Past tense of to have plus participle Action is completed with respect to the past.)

Future Perfect: I will have seen it

(Future tense of to have plus participle Action is completed with respect to the

future.)

intransitive to be the perfect tense also

Example: They are gone

Example: He is risen
